0 (year)
A year zero does not exist in the Anno Domini (AD) calendar year system commonly used to number years in the Gregorian calendar (nor in its predecessor, the Julian calendar); in this system, the year is followed directly by year . However, there is a year zero in both the astronomical year numbering system (where it coincides with the Julian year ), and the ISO 8601:2004 system, the interchange standard for all calendar numbering systems (where year zero coincides with the Gregorian year ; see conversion table). There is also a year zero in most Buddhist and Hindu calendars. Historical, astronomical and ISO year numbering systems Historians The ''Anno Domini'' era was introduced in 525 by Scythian monk Dionysius Exiguus (c. 470 – c. 544), who used it to identify the years on his Easter table. He introduced the new era to avoid using the ''Diocletian era'', based on the accession of Roman Emperor Diocletian, as he did not wish to continue the memory of a persecutor o ...

Empty Set
In mathematics, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero. Some axiomatic set theories ensure that the empty set exists by including an axiom of empty set, while in other theories, its existence can be deduced. Many possible properties of sets are vacuously true for the empty set. Any set other than the empty set is called non-empty. In some textbooks and popularizations, the empty set is referred to as the "null set". However, null set is a distinct notion within the context of measure theory, in which it describes a set of measure zero (which is not necessarily empty). The empty set may also be called the void set. Notation Common notations for the empty set include "", "\emptyset", and "∅". The latter two symbols were introduced by the Bourbaki group (specifically André Weil) in 1939, inspired by the letter Ø in the Danish and Norwegian alphabets. In the past, "0" was occasionally used as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ø (other)
''Ø (Disambiguation)'' is the seventh studio album by American metalcore band Underoath. Released on November 9, 2010, through Tooth & Nail Records, the album was the band's only without founding member Aaron Gillespie, and is the first and only record by the band with Daniel Davison, formerly of Norma Jean. It was also their final album before a two-year breakup from 2013 to 2015. They would not release another studio album until 2018's '' Erase Me''. ''Ø (Disambiguation)'' was met with acclaim and was recorded at Glow in the Dark Studios in Atlanta, Georgia, the same studio where the band's previous album, ''Lost in the Sound of Separation'' was recorded. Recording and production During a late 2009 interview, guitarist Timothy McTague stated that the band had "just started writing songs that may be included on the next record", and that they are hoping to enter the studio late summer or early fall 2010. On April 5, 2010, the band announced the departure of their final foun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Theta
Theta (, ; uppercase: Θ or ; lowercase: θ or ; grc, ''thē̂ta'' ; Modern: ''thī́ta'' ) is the eighth letter of the Greek alphabet, derived from the Phoenician letter Teth . In the system of Greek numerals, it has a value of 9. Greek In Ancient Greek, θ represented the aspirated voiceless dental plosive , but in Modern Greek it represents the voiceless dental fricative . Forms In its archaic form, θ was written as a cross within a circle (as in the Etruscan or ), and later, as a line or point in circle ( or ). The cursive form was retained by Unicode as , separate from . (There is also ). For the purpose of writing Greek text, the two can be font variants of a single character, but are also used as distinct symbols in technical and mathematical contexts. Extensive lists of examples follow below at Mathematics and Science. is also common in biblical and theological usage e.g. instead of πρόθεσις (means placing in public or laying out a corpse). ...

Zero Sharp
In the mathematical discipline of set theory, 0# (zero sharp, also 0#) is the set of true formulae about indiscernibles and order-indiscernibles in the Gödel constructible universe. It is often encoded as a subset of the integers (using Gödel numbering), or as a subset of the hereditarily finite sets, or as a real number. Its existence is unprovable in ZFC, the standard form of axiomatic set theory, but follows from a suitable large cardinal axiom. It was first introduced as a set of formulae in Silver's 1966 thesis, later published as , where it was denoted by Σ, and rediscovered by , who considered it as a subset of the natural numbers and introduced the notation O# (with a capital letter O; this later changed to the numeral '0'). Roughly speaking, if 0# exists then the universe ''V'' of sets is much larger than the universe ''L'' of constructible sets, while if it does not exist then the universe of all sets is closely approximated by the constructible sets.

Symbols For Zero
The modern numerical digit 0 is usually written as a circle, an ellipse, or a rounded rectangle. Glyphs In most modern typefaces, the height of the 0 character is the same as the other digits. However, in typefaces with text figures, the character is often shorter (x-height). Traditionally, many print typefaces made the capital letter O more rounded than the narrower, elliptical digit 0. Typewriters originally made no distinction in shape between O and 0; some models did not even have a separate key for the digit 0. The distinction came into prominence on modern character displays. The digit 0 with a dot in the centre seems to have originated as an option on IBM 3270 displays. Its appearance has continued with Taligent's command line typeface Andalé Mono. One variation used a short vertical bar instead of the dot. This could be confused with the Greek letter Theta on a badly focused display, but in practice there was no confusion because theta was not (then) a displayable ...

Slashed Zero
The slashed zero is a representation of the Arabic digit " 0" (zero) with a slash through it. The slashed zero glyph is often used to distinguish the digit "zero" ("0") from the Latin script letter " O" anywhere that the distinction needs emphasis, particularly in encoding systems, scientific and engineering applications, computer programming (such as software development), and telecommunications. It thus helps to differentiate characters that would otherwise be homoglyphs. It was commonly used during the punch card era, when programs were typically written out by hand, to avoid ambiguity when the character was later typed on a card punch. Usage The slashed zero is used in a number of fields in order to avoid confusion with the letter 'O'. It is used by computer programmers, in recording amateur radio call signs and in military radio, as logs of such contacts tend to contain both letters and numerals. The slashed zero was used on teleprinter circuits for weather applications. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
/dev/zero
is a special file in Unix-like operating systems that provides as many null characters (ASCII NUL, 0x00) as are read from it. One of the typical uses is to provide a character stream for initializing data storage. Function Read operations from return as many null characters (0x00) as requested in the read operation. Unlike , may be used as a source, not only as a sink for data. All write operations to succeed with no other effects. However, is more commonly used for this purpose. When is memory-mapped, e.g., with mmap, to the virtual address space, it is equivalent to using anonymous memory; i.e. memory not connected to any file. History was introduced in 1988 by SunOS-4.0 in order to allow a mappable BSS segment for shared libraries using anonymous memory. HP-UX 8.x introduced the MAP_ANONYMOUS flag for mmap(), which maps anonymous memory directly without a need to open . Since the late 1990s, MAP_ANONYMOUS or MAP_ANON are supported by most UNIX versions, removing the o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Kirby Characters
This is a list of characters from the Kirby franchise. These characters are featured in video games and other types of media from the franchise. Many characters have been introduced into the Kirby franchise spanning across multiple decades. Main characters Kirby is the protagonist of the series and a playable character in every game except ''Dedede's Drum Dash Deluxe''. The villains he encounters typically threaten his home of on , mostly King Dedede, or Meta Knight. The main games give Kirby the same basic abilities; he can walk, run, jump, float and inhale, as well as spit out or swallow his enemies. Following ''Kirby's Dream Land'' (1992), Kirby can gain the abilities of the enemies he swallowed, such as Fire (from Hot Head or Burning Leo), Sword (from Blade/Sword Knight), Fighter (from Knuckle Joe), and Cutter (from Sir Kibble). Kirby was originally voiced by Taeko Kawata in the ''Kirby and the Story of the Dream Spring'' (1994). Since '' Super Smash Bros.'' (1999), Kirby ...
